.738, faced with a dust-pad leaving the mantle, and thus simplify theremoval of the weight. The mantle 51 can be easily removed, since itprojects over the top of the lubrication-box. Cartridge-mantles andweights are removed before new cartridges are inserted.

The advantages shown by this modified bearing over the rst-named bearingare residing in the facts that the cartridges can be inserted farquicker direction until one of its ends clears the lug generallysupporting it, and then move the shaft in the opposite direction untilthe other end of the shaft is clearing the other lug 30.

When all parts are in position, the weights 27 will gradually press thelubricant into the central chamber 25, wherein it will duly come intocontact with the under side of the jourln the same proportion thelubricanty 27 will replace it byand more conveniently than a lubricant,which must be filled into the several channels 24, and that thelubricant contained in a cartridge can be more uniformly compressed bysuitable means independent of the bearing than the lubricant introducedinto the channels 24 by hand, whereby the pressure exerted is neveralike, for which reason layers of different densities are created whichcause an uneven lubrication. This improvement is of the greatestimportance when an axle becomes heated during a run, as the removal ofthe empty mantles and the insertion of new cartridges can beaccomplished within a few minutes.

In Figs. 7 and 8 a self-adjusting line-shaft bearing is shown in whichthe lower journalbox 53 is provided at both sides of the base 54 with auniformly-curved tubular casing 55 to permit, on the one hand, aconvenient insertion of cartridges 49, struck with the same radius asthe casing 55, and, on the other hand, an easy removal of the emptycartridge-mantle. The channel 24 of each casing 55 is gradually curvedupward and reduced at its lower end. The contracted chamber 56 thusformed pierces the bearing-surface of the lower bearing-box 53 beneaththe shaft 57. The lubricant 26 is pressed by the weight 27 into thegrooves 58, corresponding to the upper branches ofthe central chamber 25of Figs. 2 and 5. The ends of the lower bearingbox 53 are provided withrecesses 59 to collect the used lubricant. After the cartridges havebeen inserted the weights 27 are placed thereon and the caps put on thecasings 55. As soon as the shaft 57 is rotated and the lubricantconsumed theweights 27 slowly sink within the cartridge-mantlesp51, andthus keep the under side ofthe shaft 57 constantly in contact with asteadily upward pressed lubricant-cushion.

The attachment'of the tubular casings 55 to the lower bearing-box 53 andtheir arrangement at one side of the shaft 57 and at both sides of thebase 54 permits not only the most reasonable lubrication of the shaftwhere the pressure really exists, but also offers the best means for aconvenient and rapid renewal ,of the cartridges.

l claim# n 1. A bearing having a lower bearing-box provided with achamber arranged beneath the journal or shaft to be lubricated and communicating with said journal or shaft, chann nels for the reception ofthe lubricant aris consumed the weights the journal uninterruptedly incontact with a steadily upward pressed lubricant-cushion.

The car-axle bearin shown in Figs. 3- to 6, inclusive, is principa lydiering from the above-described bearing in minor details ofconstruction and by the fact that the lubriinto the channels 24 diinFig. 3 the recess 9, containing the dustguard 10, is closed by aspring-actuated cover 39, whereas the door'17 is made hollow andlikewise faced with a dust-pad 40 to replace the gasket19. (Shown inFig. 1.) To secure the lubricationbox 2, an eccentric locking-pin 41 isemployed instead of the shaft 29. (Shown in Figs.

21, the locking-pin 41 is pushed into place, with its shoulder 42 ontop,until the pintle 43 has entered L This done, the locking-pin 41 isrotated until the shoulder 42 takes .up the position shown in Fig. 3,whereby the lubrication-box 2 is secured in its working position. Thelocking-pin 41 is held in positionby the spring-catch 45, whoseprojection 46 enters a depression 47 of the pin 41. Other differencesare that the bearing-box 14 is lined with Babbitt metal and that theaperture 5 communicates with the interior of the casing 1. Fig. 6 showshow the casing 1 is guide by guide-bars 4S.

For the reason that here the lubricant is employed in shape ofcartridges 49 the channels 24 of the lubrication-box are not kept apartby division-walls, as indicated in Fig. 1, but form one common chamberin which the cartridges are placed side by side and held in position byribs 50. To better guide the lubricant standing under the iniiuence ofthe weights 27 and to prevent the cartridges deep into the centralchamber 4, the lower ends of the channels are gently curved and at thesame time drawn in, as shown in Figs. 2 and 5. 1n operation this bearingis acting similarly to the bearing described above, the only differencebeing that the weights 27 are sliding down within the cartridge-mantle51 instead of in the channel directly.

The mantle of the cartridge may be made of tin. The lower end of thecartridge-mantle is provided with indentations or inward projections 52to prevent the weight from cialis ranged sidewise ol said journal orshaft and communicating at their lower upward-sloping end with saidchamber, and an independent weight in each lateral channel forautomatic* j ally ej ecting the lubricant from the channel containing itand pressing it into and through l said chamber upward against the underside of said journal or shaft.

2. In a bearing the combination with the A journal or shaft to belubricated of a lower bearing-box having a chamber communicating withthe under sideAolI said journal or shaft, channels for the reception ofthe lul bricant arranged sidewise of said journal or l shaft andcommunicating at their lower upj ward-sloping end with said chamber, andan independent weight in each channel to eject j the lubricant containedtherein and press it j into and through said chamber upward j againstthe under side of said journal or shaft. j

3. In a bearing the combination with the journal or shaft to belubricated of a lower bearing-box having a chamber communicating withthe under side of said journal or shaft7 channels arranged sidewise ofsaid jourj nal or shaft and communicating at their lower upward-slopingend with said chamber, an eX- l changeable lubricant cartridge in eachchanr nel, and an independent weight on each lubricant-cartridge toeject the lubricant from the cartridge-mantle and press it into andthrough said chamber upward against the under side of said journal orshaft.

4. In a bearing the combination with the lower bearing-box having alchamber communicating with the under side ol the journal or shaft to belubricated and channels for the reception of the lubricant arrangedlaterally of said journal or shaft and communicating at their lowerupward-sloping end with said chamber, of a casing containing andguiding' said lower bearing-box, and an eccentric locku ing-pin held inits locking position by a spring-catch.

5. As a new article of manufacture a lubricant-cartridge comprising acurved tubular metallic mantle, inwardly-pointing proj ections at thelower end oi' said mantle, and a lubricant held by said mantle.
